7 Claims.

This invention relates to ironing machines designed primarily for use in preparing some of the materials employed in'the manufacture of shoes.

It has generally been the practice to provide the tips and/or Vamps of shoes with fabric linings or backings. With mechanisms now in use,

however, this has been done in amanner not altogether satisfactory because of the time required and of the difiiculty in properly applying the backings to the leather or other materials of the shoes.

An object of the present invention is to provide a machine by means of which the application of backings to the tips and Vamps of shoes can be speeded up and the backings applied quickly and smoothly in their proper positions.

It is a further object to provide a machine which supports the tips and/or Vamps in positions' where the operator can readily place the backings thereon after which the material is subjected to pressure and heat to cause adherence of the backings to the parts thereunder, rubber being used as an adhesive.

A further object is to provide a machine of this character which iscompact and efiicient, can be manufactured at low cost,and whichwill practically double the Work heretofore performed by a single operator.

With the foregoing and other objects in view 30 which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings:

Figure 1 is a front-elevation of the machine.

Figure 2 is a top plan view thereof.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a plan view of a portion of one of ence l designates a supporting frame of anysuitableconstruction on which is mounted a table 2 the front of which is shaped to define a V- shaped recess formed by forwardly diverging edges 3 extending from the center of the front of the table.

guides ,4 project. Thus the plates are guided in their back and forth movement.

Each carrier can be of any size desired and can be proportioned to hold one piece of the work to be: ironed or a couple of pieces. Adjacentto the back edge of each carrier there are provided stop pins 6' the lower ends of which are mounted to slide in recesses l in the carrier, these recesses containing springs 8 which support the upper ends of the pins normally projected above the carrier. Thus" when the work is placed on the carrierthese pins constitute stops for limiting sliding movement of the work backwardly while being: placed in position. In other words these stop pins constitute abutments for the work when in theirnormal positions. This will be apparent byreferring to Figures 4 and 5 wherein the work has been indicated generally at W. Obviously any desired number of these stop pins can be used on each carrier, depending upon the nature and location of the worki Studs 9 extend: downwardly from each carrier at points adjacent to the centers of the front and backedges thereof and these studs are adapted to work freelywithin slots IE] formed in the table 2. A groove I [is preferably formed in-the bottom of each carrier and inline with the studs and into thisgroove projects the upper end of a shaft l2 jo'ur'nalled'in suitable bearings l3 in the frame and provided at its" lower end with'a gear M. A cam I6 is secured to this shaft l2 and works between the studs 9' so as to alternately thrust against the studs, the cam being so shaped, as indicated in Figure 2 as to successively thrust the carrier backwardly and forwardly 'with pauses in between said movements of sufficient duration to afford the operator 'ample opportunity to remove work from the carrier and place new work thereon.

Gear l4 meshes with a gear ll secured to a transverse shaft I8 journalled in frame I and this shaft is adapted to receive motion in any suitable manner from an electric motor l9 or other suitable operating means.

In the structure shown the motor I9 transmits motion through chain and sprocket mechanism 20 to a reduction gearing indicated generally at 2| and motion is then transmitted through chain and sprocket mechanism 22 from the reduction gearing to the shaft [8. It is to be understood, of course, that the shaft I8 is used for driving the shaft 12 of both cams I6. By referring to! Figure 2 it will be seen that the cams are oppositely disposed so that when one carrier is moving forwardly the other carrier 5 is moving rearwardly.

Extending upwardly from table 2 are angular guides 23 and located adjacent to each guide is an upwardly extending pin 24 on which is mounted a spring 25. A heating and pressing head 26 is slidably mounted at its corner portions on the pins 24 and between the guides 23. Each of these heads is yieldingly supported by the springs 25 and is provided, near its center, with a thrust-receiving portion 21.

Standards 28 are mounted on the table and serve to support a shelf 29 on which work can be placed. These standards have bearings 30 in which is journalled a shaft 3! and'secured to the shaft above each of the thrust portions 21 is a cam 32. The two cams are extended in opposite directions as shown in Figure 1 and are adapted alternately to engage the respective thrust portions 21 when shaft 3| rotates. Mo-

' tion is transmitted to shaft 3| in any suitable manner, as by means of chain and sprocket mechanism 33 extending from shaft I8.

Each of the heating and pressing heads is provided with suitable heating means. This heating means can be in the form of electric heating elements 34 contained therein and where such elements are used, pilot lights can be employed to indicate when they have reached the proper temperature. Switches 36 can be used for controlling the heating units.

The cams 32 are arranged to operate in properly timed relation to the cams l6 so that each of the heads 26 will be pressed downwardly at the beginning of the pause following the positioning of the carrier under said head and will be released immediately preceding the termination of said pause. Obviously as soon as each head 26 is released, the compressed spring 25 thereunder will raise the head out of contact with the work W on the carrier thereunder.

When it is desired to use the machine the operator takes a position in front of the center of the table so that by turning slightly to the right or to the left one or the other of the carriers can be readily reached for the purpose of placing work thereon or removing work there: from. When the machine is set in motion one of the carriers is thrust forwardly while the other isthrust rearwardly and when these car- "riers reach the limit of their movement, they remain stationary for a sufficiently long period to enable the operator to place the Work thereon or remove it therefrom. When a carrier reaches its forward position, the operator places thereon the materials to be pressed and heated. In the structure shown the work comprises a whole shoe vamp and quarters indicated at S and backing pieces B formed of fabric rubber-coated on the underside, the coating constituting an adhesive. The parts are position-ed so as to be supported smoothly on the carrier and it will be noted that the pins 6' prevent these parts from being pushed backwardly too far thereon.. As

:"soon as the Work has been placed on the carrier the operator turns so as to be in position to remove work from the other carrier. Following the predetermined pause in movement, the carrier on which work had been placed is thrust rearwardly into position under its heating and pressing heads and as it reaches said position, said heating and pressing head is thrust downwardly against the action of the springs 25 so as to press firmly on the work and subject it to heat as well as pressure. At this time there is a pause in the movement of the carrier and during this pause the other carrier is located at the front of the table where the Work can be removed and new work placed thereon. Immediately prior to the termination of the pause, the depressed head 26 is released so as to lift away from the work and thereafter the carriers begin their movement so that the pressed work is brought forwardly by one carrier and a new supply of work is moved rearwardly by its carrier into position below the heating and pressing head provided therefor. The operation already described is then repeated.

Attention is called tothe fact that every time a head 26 is lowered, it pushes downwardly on the pins 6 so as to lower them. Consequently these pins offer no resistance to the pressing and heating operation.

It has been found that a machine of this type will greatly increase the output of tips, Vamps and quarters lined with affixed pieces and the work produced has been found free from imperfections because the operator has ample time in which to properly place the work upon the carriers and the heads 26 act efficiently to press and to heat thework.

The pieces prepared for placement on the carriers can be supported on shelf 29 until they are to be used. This shelf isat all times in convenient reach of the operator.

While it is preferred to form the machine with two complete units, as shown, it is to be understood that smaller machines could be made with one unit including the one carrier and one head or, in larger machines, more than two units could be used, all extending radially from the operator.

While the machine is designed primarily for heating'and pressing parts of shoes, it is to be understood that it can be employed in the production of other articles requiring the application of two or more layers of material under heat and pressure.
